You might not think birds are an affectionate type of pet, but there are certain species that are more affectionate and cuddly than others. Usually the small parrots are the more affectionate type. Birds that make the cuddly list include cockatiels, cockatoos, budgies (also known as parakeets).
These birds enjoy time with humans and require regular out of cage play time. How do you know if your bird is showing you affection? If your bird perches on you or is being playful and gently nip at you with his beak or tries to groom you, he is showing you affection. Of course, if your bird is chattering or seems to be talking to you in an exited voice, that is also a good sign!
